Season 5

Houses featured include a home in Eton made entirely from cork, an innovative Derbyshire stone cottage, and an extraordinary ultra-low-energy house in Buckinghamshire.

A striking stone property in the middle of a nature reserve, a family home tucked away in south London, and a black timber box in Skye are some of the designs on view.

The contenders this time include a stylish property in Devon, designed by a master architect, and a sleek, elegant home in Northern Ireland.

Kevin looks at homes which excel in craftsmanship and materials before the overall winner of the grand prize of House of the Year 2019 is revealed.
